The best time to ask payment questions is before money moves. Once you have paid, your leverage and options can change quickly.
These questions are not about catching someone out. Good builders should be able to answer them because clear payment terms protect them too.
Before paying a deposit
Ask:
- What exactly does this deposit cover?
- Is any part of it refundable?
- What date will work start?
- What happens if the start date changes?
- Are materials being ordered now?
- Will I receive order confirmations or receipts?
- Is there deposit protection or insurance?
If the answer is vague, ask for the payment to be split into smaller stages.
Before paying for materials
Materials payments are common, but they should be specific.
Ask:
- What materials are being bought?
- Who owns them once paid for?
- Where will they be stored?
- What happens if they are delayed?
- Are any items bespoke or non-refundable?
A real materials payment should have real material details.
Before paying a progress invoice
Progress payments should match progress.
Ask:
- Which milestone is this payment for?
- Has the stage been completed?
- What evidence confirms completion?
- Are there any outstanding defects or changes?
- What is the next payment trigger?
If the invoice is based only on a date, ask to connect it to completed work.
Before paying the final invoice
The final payment should close the job cleanly.
Ask:
- Is the agreed scope complete?
- Are snagging items documented?
- Have certificates, manuals, or warranties been provided?
- Has waste been removed?
- Are all subcontractor costs included?
- What happens if a defect appears shortly after completion?
Do not leave important completion details informal.
The question that matters most
The strongest single question is: what has to be true for this payment to be due?
If both sides can answer that clearly, the payment is probably better structured. If nobody can answer it, the risk is still too vague.

FAQ
Is it rude to ask these questions?
No. Clear questions reduce disputes. Professional builders should expect payment terms to be discussed before work starts.
What if the builder refuses to answer?
Do not pay until the terms are clear. A refusal to explain payment is a meaningful warning sign.
Should I get answers in writing?
Yes. Messages, email, quotes, and invoices all help create a record of what was agreed.
